GRATE Filed Dec. 26, 1951 WITNESS: INVENTOR Iraclemck 1:]- canardPatented Dec. 19, r 1933 UNITED STATES PATENT OFFICE ApplicationDecember 26, 1931 Serial No. 583,296

2 Claims.

This invention relates to grates, and has for an object to provide agrate for supporting a fire in a stove, furnace, or the like, and havingimproved features for folding the grate for inserting and withdrawing.

A further object of the invention is to provide a grate having hingeslocated upon the under side along a diametrical line, which diametricalline forms the abutting of the two sections of the grate.

A further object of the invention is to provide a grate divided intohalves, each half being provided with hinge members identical in bothhalves, and reversible to coact with the hinge members on the otherhalf. I

The invention therefore comprises a grate having grate bars spaced apartfor the support of fuel and the introduction of air, two of said gratebars abutting against each other at a median line, with hinges formed ascorresponding and identical members upon the underside of the grate barsections serving to hinge the grate so that it may be folded intoone-half its original width.v

The drawing illustrates an embodiment of the invention and the viewstherein are as follows:

Figure 1 is an inverted plan view of the grate,

Figure 2 is a view of the grate in edge elevation, as indicated by arrow2 at Figure 1, and

Figure 3 is an edge view of the grate folded.

Like characters of reference indicate corresponding parts throughout theseveral views.

The grate of the present invention is intended to be exemplified in acircular grate, indicated at 10, although it is to be understood that itmay apply to grates other than circular. The grate is provided withsubstantially the usual and ordinary grate bars 11, with the interveningspaces for the introduction of air, and the passage of ash. The gratebars which extend substantially diametrical of the grate, are indicatedas 12, the halves of the bars 12 being identical. The bars are eachprovided with hinge members 13 at one end and 14 at the opposite end, soarranged that each will co-act with the other. A pintle l5 completes thehinge and the completion of the hinge completes the grate as a unitarystructure. In operative position, as supporting a fire, it will be asshown at Figures 1 and 2, that is to say, extended to its full width.For the purpose of inserting or withdrawing, for instance through a firedoor, the grate may be folded as shown at Figure 3 so that it willoccupy a lesser area- The grate, while adapted for general use, is

coal known as egg.

more particularly intended as a repair grate, or

a replacement grate, or applying to a heating unit for the support offuel of different grade or size. As an example, the grate of a heatingunit might be such as to properly support that size of 60 For thepurpose of fitting the heating unit, to employ a smaller size, as forinstance buckwheat which is a cheaper fuel, this replacement orsupporting grate, here illustrated, will be employed with the barsproperly spaced for the purpose. By folding the grate as shown, it ispossible to insert or withdraw it through the fire or stroke doorwithout tearing the heating unit apart.

Of course, the grate, herein illustrated, may be modified and changed invarious ways without departing from the invention herein set forth andhereinafter claimed.

The invention is hereby claimed as follows:

. 1. A grate comprising two approximately identical sections; eachhaving one straight edge, each section having hinge-ears formed upon itsunder side at said straight edge, the ear adjacent one end being spacedfarther from the perimeter than the ear at the other end, said ears ofthe sections being so relatively positioned that when mated theymaintain the united sections in a symmetrical unit.

2. A grate comprising two approximately identical semi-circularsections, each section having hinge-ears formed upon its under side, theear adjacent one end being spaced farther from the perimeter than thecar at the other end, said ears of the sections being so relativelypositioned that when mated they maintain the united sections in acircular unit, and diametrical bars abutting to maintain planarity ofthe grate surface opposite the ears.
